avermectins

In the present study, to further explore the etiology of HPND, the diseased crabs with HPND were collected from Yangcheng Lake Modern Agriculture Development Company, Suzhou, China, observation of the ultrathin section of tissues from the diseased crabs were observed with a transmission electron microscope and animal regression test were performed, moreover, toxic effect of avermectin and high pH water on crabs was also examined, the results indicated that HPND was not caused by virus or microsporidian and might be induced by water of high pH value and other environmental factors.
